How do we know Christ's resurrection and ascension is true?

The truth of Christ's resurrection is supported by the eyewitness accounts documented in the Gospels and the book of Acts, where he appeared to over 500 people after his resurrection. His ascension is recorded in Acts 1:9-11, which describes how he was taken up in their sight. Additionally, the rapid growth of the early church and the resilience of the apostles underscore the reality of these events. They preached boldly about the risen Christ despite persecution, a testament to their conviction in his resurrection and reign from heaven.
